【摘要】 DSC系列公用数据采集器是数字化地震前兆台站的基本和关键性设备之一,雷电干扰常会造成数采内部芯片和元件损坏。本文通过对数采雷害故障特征分析和诊断修复,认为感应雷害是造成数采损坏的主要原因,数采内部A/D转换通道程控放大电路的ICL7650集成运放块易遭雷击损坏,是故障率较高部分。更多还原

【Abstract】 The public data collector in DSC series is one of important and key equipment in digital seismic station,but its chip or element was always destroyed by thunderbolt.Through analysis and diagnosis of the thunderbolt influence,I think the thunderbolt is the main cause to destroy the public data collector and the chip ICL7650.更多还原
